None of those cases went to trial and had Constitutional scholars and lawyers take the stand to discus the merits of presidential eligibility. The cases never even made it to the discovery phase.
Actually most of those cases went to trial. The four lawsuits in Georgia went to a “trial on the merits” as did the New Jersey cases. Tracy Fair had a hearing and the chance to present evidence to a judge in Maryland. The Illinois ballot challenges had hearings before the Illinois Board of Elections.
Ankeny was an appeal of a case that went to trial in Indiana and Strunk had a trial in New York. Strunk angered the judge so much that the judge assessed $177,000 in court costs against him.
Lawsuit trials are not the same as criminal trials. They are often wrapped up in a single hearing.
